There's a bug in Go's
strings.Titlefunction which prevents it from recognizing words separated by certain unicode punctuation marks. In Go 1.18,strings.Titlewill be deprecated. This replaces that usage withgolang.org/x/text/cases, as suggested by the Go 1.18 documentation.I've also updated the
ToUpperandToLowerfunctions accordingly, and added the ability to later define a specific BCP 47 language tag (not yet sure how, but the plumbing is laid).Signed-off-by: Dave Henderson [email protected]
